What is magnet and types? Permanent magnets are magnets that retain their magnetism once magnetized. Temporary magnets are materials magnets that perform like permanent magnets when in the presence of a magnetic field, but lose magnetism when not in a magnetic field. Below we breakdown the various types of magnet available. What are the main […]

Does changing current affect voltage? To answer this question, the relationship between the voltage and current variables given must be specified. and thus that the current will change proportionally with the voltage. and thus the current will change exponentially with the voltage. Does higher voltage draw less current? If the voltage out is twice that […]

What is the egg drop problem? Egg dropping refers to a class of problems in which it is important to find the correct response without exceeding a (low) number of certain failure states. In a toy example, there is a tower of n floors, and an egg dropper with m ideal eggs. What does Ojo […]

When a spoon is in a glass half full of water Why does the spoon look like it is broken in the middle? It is refraction due to which we saw spoon broken near water surface. 1. If you put a coin inside glass of water and view it from the top then coin appears […]

What force is needed to give a 2000 kg car? The net force needed is 4000 N . How long will it take to walk 10km? 90 minutes to two hours How many minutes is 25 miles? It is possible to go 25 miles on the interstate in 30 minutes. It can take anywhere from […]

Does more water make plants grow faster? Water helps a plant by transporting important nutrients through the plant. With outdoor plants, you can’t control the plants getting too much water if your area gets a lot of rain, so you need to make sure that the soil has the proper drainage, because too much water […]

Can a meteor hit the sun? No asteroids have ever been observed to hit the Sun, but that doesn’t mean that they don’t! Orbits within in a Kirkwood gap are not stable, and any asteroid whose orbit wanders into such a region will eventually get pulled into a different orbit, which may take it into […]

What do u mean by runoff? noun. something that drains or flows off, as rain that flows off from the land in streams. What is difference between runoff and streamflow? Streamflow, or channel runoff, is the flow of water in streams, rivers, and other channels, and is a major element of the water cycle. It […]

Which router is elected as the DR? Two rules are used to elect a DR and BDR: router with the highest OSPF priority will become a DR. By default, all routers have a priority of 1. if there is a tie, a router with the highest router ID wins the election. What will an OSPF […]

What happens when a gas expands at constant temperature? Therefore, at a constant temperature, the kinetic energy will also be the same. Therefore, when gas expands at a constant temperature, pressure decreases as well as kinetic energy of the molecules will remain the same. What happens to pressure when gas expands? When the gas expands […]
